Great game. I love how unwieldy the truck gets once you start pulling a big load. I got real upset at the jerk drivers scooting around the galaxy like they own the place!
The art looks nice and the music is good (but it does start playing on top of itself if you restart the game, haha!) What I really think this game needs is some sound and small visual effects to really sell the fact that you're driving a truck with huge, heavy metal boxes. But other than that, the mechanics in the game feel right, and it game plays well and looks great. Nice job!
